FILTER.

SPECIFICATION forming part of Letters Patent No. 230,347, dated July 20,1880,

Application tiled May 1, 1880. (No model.)

To all whom zt may concern Be it known that we, ROGER F. SCANNELL andJOHN E. LrPscoMBE, both of Boston, in the county of Sulfolk and State ofMassachusetts,haveinvented anew and useful Improvement in Filters, ofwhich the following is a specification.

rlhis invention is an improvement upon the filter for which LettersPatent Were granted io'us April 6, 1880, saidLetters Patent beingnumbered 226,243; and the said improvement relates entirely to the plug,which is supplied with a certain additional channel or hole andenlargements of certain portions of channels shown in the said previousinvention, by

means of which the water may not only be liltered and pass throughunfiltered, and the lilter be cleansed by reversing it, so that thewater passes rst through pipe g in said patent zo and then through thecharcoal, but in addition to all this, which is accomplished in saidpatented invention, the water remaining in the lilter after thereversing cleansing process may itself be ltered by passing it iirstthrough the charcoal and then through pipe g and then out through awaste-pipe. In other Words, an additional means for cleansing isprovided, which cleanses the water left in the filter and passes itthrough the ilter without reversing 3o its direction.

In theaccompanying drawings, in which similar letters of referenceindicate like parts,

Figure l is a longitudinal vertical section of the filter described insaid Letters Patent v 3 5 with our present improvement applied to theplug in position for filtering. Fig. 2is a similar section with the plugreversed for cleansing in the manner described in said patent. Fig. 3 isasimilar section with the plug in position for the final cleansingaccomplished by means of our improvement.

Fig. 4 is a horizontal section with the plug in the position shown inFig. 1. Fig. 5 is a cross vertical sec tion of the plug, taken throughthe central hole therein.

5o plate b.

D is the faucet or cock, having passages c and f, the former leading tothe carbonchamber A and the latter to the vertical tube g in saidchamber. Passages 7L and 7c lead respectively to the supply-pipe E andthe housepipe F, and passage l to thc waste-pipe G, and all saidpassages connect with the plug H. The plug H is provided with thechannelsp q s, the hole t, and pointer m.

All the above parts are constructed and arranged as described in thesaid Letters Patent. Their operation is, briefly, asfollows: To liltcrthe Water, turn the plug by means ofthe pointer m into the positionshown in Figs. l and 4. The water enters through passage h in thesupply-pipe E, passesthrough passage p in the plug and passage 'c in thefaucet, up

through the carbon in the chamber A, down through tube g,faucet-passagef, plug-passage q, and passage lo in the house-pipe F.

To cleanse the filter, reverse the plug by means of the pointer m, sothat it is in the position shown in Fig. 2. The water passes frompassage h through channel q, passage f, up

through tube g, down through the carbon, through passage c, channel s,hole t, and pas sage l, into the waste-pipe G.

It will readily be seen that after the cleansing process above describedthere is still a tilterful of water, (amounting to some gallons,) Which,as soon as the plug is turned so as to let the water on to the house,must pass to the house, carrying impurities with it. By means of theimprovement below described this lterful of water, instead of beingturned back into the house, is turned back through the lter, as thoughit were going to the house, but is instead conducted to the waste-pipe.

In this improvement aconnectiomp, is made at the central end of thechannelp by removing a portion of the plug at that point, and a similarconnection, s', is made at the central end of the channel s. Also a holeor channel,

as desired, ism-ade, as shown by n, Figs.3 and 4. This hole or channelterminates in the hole t, and its course is shown in the two figuresnamed. The more direct way is to carry it directly to the hole t byboring the plug, thus making a straight hole, as shown in broken lines,Figs. 4 and 5 5 but either a hole or channel is satisfactory.

The operation is as, follows After the IOO reversing process, the plugbeing in the position shown in Fig. 2, turn the plug threeeighths of aturn to the lef't, as shown in Fig. 8. This brings the part p of thechannel 19 into connection with the passage h in the supply-pipe E, theopposite end of passage p (or a part near to the opposite end) intoconnection with the passage c, the end fu of s, which enters the holet,into the passage Zot' the waste-pipe G.

Ilhus it will be seen that this cleansing process carries the waterthrough the carbon before carrying it through pipe or tube g. Thecleansing process described in the Letters Patent above alluded to didjust the reverse of this.

In this improved supplementary cleansing process the water goes throughthesanie Way as when being filtered.

Having thus fully described our improvement, what we claim, and desireto secure by Letters Patent, is-

In combination with the faucet D, provided with passages afl, the plugH, provided with hole t, connection s', channel p and connection p. andholeor channel o o', arranged and coulstructed to operate substantiallyas and for the purpose herein set forth.
